Risk Assessment, Site Remediation and Demolition Services Performed

MASSACHUSETTS, WESTFORD, Apr. 19 -/E-Wire/-- ENSR International, a leading environmental services firm, recently completed a major multi-phase site remediation program for the Fort James Corporation (now Georgia-Pacific). At the former paper mill complex in New Jersey, ENSR successfully obtained a No Further Action (NFA) designation from the state agency and addressed risks to human health and the environment, remediated and restored the site, saving Fort James/Georgia-Pacific substantial potential cleanup costs.

"ENSR is extremely pleased to have led the Industrial Site Recovery Act (ISRA) remediation and risk assessment effort at the site," said ENSR's David Mitchell. "We helped Fort James/Georgia-Pacific cost-effectively remediate or recycle tons of hazardous and nonhazardous metals and/or PCB-contaminated solids, metal debris and asbestos-containing or suspect building materials and obtain an NFA designation from the State. New Jersey's "Green Acres" program will be acquiring the scenic site to be used potentially for recreational purposesâa real case of turning brownfields green.

Adjacent to the Delaware and Musconetcong Rivers, the former Riegel Products site in northern New Jersey manufactured paper for 100 years until operations ceased in the early 1980s. After decades of industrial use, by-products of mill operations (polychlorinated biphenyls or PCBs, chromium and copper) were detected in site soils, potentially impacting nearby soil and riverways and threatening area human health and ecology.

During the initial stages of the project, ENSR conducted Human Health and Ecological Risk Assessments at the site, performed a Baseline Ecological Evaluation and negotiated with the New Jersey Department of Environmental Protection (NJDEP). Risk assessment findings were used to develop Alternate Cleanup Standards (ACS) for PCBs, chromium and copper in surface and subsurface soil. These ACS resulted in successful risk-based alternate clean-up standards for remediation of this site, which protected human health and the ecology, producing the significant savings for Ft. James.

The site consisted of over 12 large buildings over a two-acre area. ENSR developed a comprehensive Decontamination, Demolition and Waste Management Plan to address: PCB contaminated building walls and floors; equipment and piping; and interior building residuals for offsite disposal and/or recycling. Approximately 13,000 tons of materials were removed during the building decontamination. In addition, an innovative approach was used successfully to dismantle and demolish a concrete/brick building spanning an ecologically sensitive waterway.

A "master" ACS checklist, designed to help a wide range of companies identify alternative cleanup solutions and realize cost savings, is now available from ENSR. The list addresses: older brownfields sites with limited, nonexistent or nonanticipated residential redevelopment potential; (cont'd)

sites with atypical contaminants for which no state standards exists; sites located along major waterways for which complex fate and transport models need to be developed to understand site impacts; and sites located adjacent to environmentally sensitive areas or protected species habitats.
